|
Mass of an electron is about 1/1800th of the lightest nucleus.

Detailed explanation-1: –The difference between positron and proton is mass, positron has the same mass as electron. Protons are approximately 1836 heavier than electrons or positrons. Now, we know that positrons are anti – particles of electrons. Therefore, the mass of the electron and positron will be the same.
Detailed explanation-2: -Proton is ionized hydrogen i.e. H+. It contains only protons and no neutrons or electrons. Was this answer helpful?
Detailed explanation-3: -The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron.
Detailed explanation-4: -A positron has the equal or same mass as an electron and a spin of 1/2, but it has an electrical charge of +1.
